slip a cog

To become mentally unbalanced, disturbed, or confused. Usually used humorously or facetiously. Sorry, I must have slipped a cog, because I have no idea what I was talking about just now. Grandpa, I think you've slipped a cog—I've never heard of that movie and I can't find it anywhere online!

cog in the wheel

Also, cog in the machine. One who holds a minor but necessary post in a large organization, as in Frank knew he was just a cog in the wheel of this giant corporation. This term alludes to the role of the mechanical cog, one of the teeth on a wheel or gear that, by engaging other teeth, transmits or receives motion. Used figuratively since about 1930, it sometimes is put as small cog in a large wheel, emphasizing a person's lack of importance.

slip a cog

Also, slip a gear or one's gears . Lose one's ability to reason soundly or make correct judgments, as in She must have slipped a cog or she would never have gone out barefoot in December, or What's the matter with him? Has he slipped his gears? These slangy usages allude to a mechanical failure owing to the cog of a gear or a gear failing to mesh. The first dates from about 1930, the variant from the 1960s.

Although the cogging torque that is generated by the zero coil current has not decreased, reduction in the peaks of the coenergy and the torque factor is realized according to these figures.
Although calculated cogging torque that is generated by the zero coil current is unchanged, the energy variation in the curve illustrates the reduction of the torque ripple (Fig.

New Stator Tooth for Reducing Torque Ripple in Outer Rotor Permanent Magnet Machine
As a function of the angle rotation of the rotor without and with the pole shifting, the cogging torque values of the PMSG are comparatively given in Fig.
The reducing of the cogging torque on the PMSG will make a great advantage for electricity generation of the MWT.
It is demanded that PMSGs have low cogging torque values in industries in which they are used.
In parallel with this purpose, in this study, a pole shifting technique not bringing additional cost to the manufacturers has been successfully applied to reduce the cogging torque.

The percentage reduction of cogging torque by this method is 89.33 which is greater than that achieved by all the above methods.
After the application of each method of cogging torque reduction in DRFPMG, the change in induced emf has been evaluated.
In the shifting of slot openings method, the cogging torque was suitably reduced and the induced emf is better than other methods as seen in Table 3.
The experimental measurement of induced emf and power and cogging torque of DRFPMG prototype was carried out using a laboratory set-up shown in Figure 14.
The cogging torque of DRFPMG prototype was measured with piezo electric reaction torque sensor.
